It may be possible if you have a 32 bit version of Windows 7. (IIRC,
there are folks on the WordStar list who deliberately got a 32 bit
version of Win 7 so they could still run WS7 in it. Win7 is the last
version of Windows that has a 32 bit version. Win8 is straight 64
bit.)
It is *not* possible in 64 bit versions. Native support for 16 bit
applications was dropped. The only way to do it in 64 bit Windows is
to run a virtual machine. If you have Windows 7 Pro, you can get
Microsoft's VM software and an XP image to run in it, then run the DOS
stuff in the XP VM. Others have reported some success with
Oracle/Sun's open source VirtualBox VM software, or using VMWare
Workstation. Expect to fiddle, regardless.
